The technical solutions of the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which are derived by a person skilled in the art based on the embodiments of the application, fall within the scope of protection of the application.

Fig. 1 shows a block diagram of a wireless communication system to which an embodiment of the present application is applicable. The wireless communication system includes a terminal device 11 and a network device 12. The terminal device 11 may be a Mobile phone, a tablet pc (Tablet Personal Computer), a Laptop (Laptop Computer) or a so-called notebook, a Personal digital assistant (Personal DIGITAL ASSISTANT, PDA), a palm top, a netbook, an ultra-Mobile Personal Computer (ultra-Mobile Personal Computer, UMPC), a Mobile internet device (Mobile INTERNET DEVICE, MID), augmented reality (augmented reality, AR)/Virtual Reality (VR) device, robot, wearable device (Wearable Device), vehicle-mounted device (VUE), pedestrian terminal (PUE), smart home (home device with wireless communication function such as refrigerator, television, washing machine or furniture), game machine, personal computer (personal computer, PC), teller machine or self-help machine, and other terminal side devices, the wearable device including: intelligent watch, Intelligent bracelet, intelligent earphone, intelligent glasses, intelligent jewelry (intelligent bracelet, intelligent ring, intelligent necklace, intelligent anklet, intelligent foot chain, etc.), intelligent wristband, intelligent clothing, etc. It should be noted that the specific type of the terminal device 11 is not limited in the embodiment of the present application. The network-side device 12 may include an access network device or a core network device, where the access network device 12 may also be referred to as a radio access network device, a radio access network (Radio Access Network, RAN), a radio access network function, or a radio access network element. Access network device 12 may include base stations, which may be referred to as node bs, evolved node bs (enbs), access points, base transceiver stations (Base Transceiver Station, BTSs), radio base stations, radio transceivers, basic SERVICE SET, BSS, extended SERVICE SET, ESS, home node bs, home evolved node bs, transmit and receive points (TRANSMITTING RECEIVING points, TRP) or some other suitable term in the field, the base station is not limited to a specific technical vocabulary as long as the same technical effect is achieved, and it should be noted that in the embodiment of the present application, only the base station in the NR system is described as an example, and the specific type of the base station is not limited. The core network device may include, but is not limited to, at least one of: a core network node, a core network function, a Mobility management entity (Mobility MANAGEMENT ENTITY, MME), an access Mobility management function (ACCESS AND Mobility Management Function, AMF), a session management function (Session Management Function, SMF), a user plane function (User Plane Function, UPF), a policy control function (Policy Control Function, PCF), policy AND CHARGING Rules Function (PCRF), edge application service discovery Function (Edge Application Server Discovery Function, EASDF), unified data management (Unified DATA MANAGEMENT, UDM), unified data repository (Unified Data Repository, UDR), home subscriber server (Home Subscriber Server, HSS), centralized network configuration (Centralized network configuration, CNC), network storage functions (Network Repository Function, NRF), network open functions (Network Exposure Function, NEF), local NEF (or L-NEF), binding support functions (Binding Support Function, BSF), application functions (Application Function, AF), and the like. It should be noted that, in the embodiment of the present application, only the core network device in the NR system is described as an example, and the specific type of the core network device is not limited.

The terminal device can perform uplink transmission and downlink transmission simultaneously in a full duplex mode. Referring to fig. 2, a symmetrical spectrum diagram of frequency division duplexing (Frequency Division Duplexing, FDD) in full duplex mode is shown. As shown in fig. 2, the uplink or downlink spectrum of FDD may be semi-statically configured or dynamically indicated as downlink or uplink on certain slots/symbols. Referring to fig. 3, an asymmetric spectral diagram of time division duplexing (Time Division Duplexing, TDD) in full duplex mode is shown. As shown in fig. 3, different frequency domain resources on certain time slots or symbols of TDD may be semi-statically configured or dynamically indicated as having both uplink and downlink transmissions. For a terminal in half duplex mode, only uplink transmission or downlink transmission can be performed at the same time, i.e. the terminal cannot both receive and transmit signals at the same time. As shown in fig. 4-1, a symmetrical spectrum diagram of FDD in half-duplex mode. In half duplex mode, as shown in fig. 4-1, the uplink or downlink spectrum of FDD can only be transmitted uplink or downlink on certain timeslots/symbols. Similarly, as shown in fig. 4-2, in half duplex mode, different frequency domain resources on some timeslots or symbols of TDD can only be used for uplink or downlink transmission.

In order to realize flexible network deployment, the transmission direction of each symbol in a time slot is configured in a New Radio (NR) system by means of a slot format (slot format).

Referring to fig. 5, a schematic diagram of a slot format is shown, and as shown in fig. 5, the transmission direction of a slot in NR has three definitions, downlink (DL), uplink (UL), and flexible. When the network configures a time slot or a symbol as DL or UL, the transmission direction at the moment is clear; when the network is configured with a slot or symbol that is flexible, the transmission direction at that time is pending. The network may modify the transmission direction of slots or symbols of the flexible by dynamic signaling, such as DYNAMIC SFI (slot format indicator).

One slot may contain downlink, uplink and flexible OFDM symbols; the Flexible symbols may be rewritten as downlink or uplink symbols.

The network side device may indicate the format of one or more slots by a slot format indication (slot format indicator, SFI). The SFI is transmitted in a physical downlink control channel (Physical Downlink Control Channel, PDCCH). The network side equipment can flexibly change the slot format according to the requirement through the SFI so as to meet the service transmission requirement. The UE decides whether to monitor the PDCCH according to the indication of the SFI.

Illustratively, the base station may semi-statically configure the UE with one or more cell-specific (cell-specific) slot formats via the higher layer parameters UL-DL-configuration-common and UL-DL-configuration-common-Set 2. The base station may also configure one or more UE-specific (UE-specific) slots by the higher layer parameters UL-DL-configuration-defined semi-statically for the UE. The base station can rewrite the flexible symbol or slot in the semi-static configuration through the SFI carried in the GC-PDCCH.

The transmission direction implicitly indicated by the UE-specific radio resource control (Radio Resource Control, RRC) configuration is commonly referred to as measurement (measurement), and may specifically include any of the following:

periodic or semi-continuous channel Sounding reference signal (CHANNEL STATE Information-REFERENCE SIGNAL, CSI-RS) measurement of UE-specific RRC signaling configuration, periodic CSI reporting, and uplink and downlink transmission directions implicitly indicated by a periodic or semi-continuous Sounding reference signal (Sounding REFERENCE SIGNAL, SRS);

Physical Random access channel (ACCESS CHANNEL, PRACH) resources configured by dedicated RRC of UE, type1 and type2 unlicensed uplink transmission;

For type2 unlicensed uplink transmission, only the transmission on the first active resource can be used as UE-specific data (UE-SPECIFIC DATA).

The UE-specific transmission may include a Physical downlink shared channel (Physical Downlink SHARED CHANNEL, PDCSH), a Physical Uplink shared channel (Physical Uplink SHARED CHANNEL, PUSCH), a/N feedback of PDSCH, aperiodic measurement triggered by downlink control information (Downlink Control Information, DCI), and the like.

In the related art, the terminal device performs transmission of uplink data/control channel according to a parameter indicated by an uplink scheduling signaling (UL grant) by the network device, or performs reception of downlink data/control channel according to a parameter indicated by a downlink scheduling signaling (DL grant) by the network device. However, the parameter indication manner of uplink transmission or downlink transmission in the related art is not well suited for UE transmission in full duplex mode.

According to the transmission parameter configuration method provided by the embodiment of the application, the terminal equipment can correspondingly change the transmission parameter configuration based on the uplink scheduling signaling or the downlink scheduling signaling of the network side equipment, so that the network side equipment can flexibly schedule the UE to carry out uplink transmission and/or downlink transmission.

The transmission parameter configuration method provided by the embodiment of the application is described in detail below through some embodiments and application scenarios thereof with reference to the accompanying drawings.

In a first aspect, an embodiment of the present application provides a transmission parameter configuration method. Referring to fig. 6, a flowchart of a transmission parameter configuration method provided by an embodiment of the present application is shown. The method is applied to the terminal equipment, as shown in fig. 6, and the method specifically can include:

Step 101, a terminal device receives downlink scheduling signaling or uplink scheduling signaling in a first time domain unit;

102, the terminal equipment determines a first transmission parameter corresponding to uplink transmission of a second time domain unit according to the downlink scheduling signaling; or the terminal equipment determines a second transmission parameter corresponding to the downlink transmission of the second time domain unit according to the uplink scheduling signaling.

In the embodiment of the present application, the terminal device may receive downlink scheduling signaling (DL grant) or uplink scheduling signaling (UL grant) in the first time domain unit. The DL grant and the UL grant may be transmitted by a network side device. The first time domain unit and the second time domain unit may be any scheduling unit of time domain resources, such as a frame, a subframe, a slot, a symbol, and the like.

uplink power control parameters;

A first spatial attribute parameter.

a second spatial attribute parameter;

It should be noted that, the downlink scheduling signaling may schedule downlink transmission of any time domain unit. Similarly, the uplink scheduling signaling may schedule uplink transmission of any time domain unit.

The uplink power control parameters may include open loop power control parameters, transmit power control (Transmit Power Control, TPC) parameters, and the like.

In the embodiment of the application, when the terminal equipment sends uplink transmission or receives downlink transmission, the transmission parameters of the current transmission mode can be configured and adapted according to the received downlink scheduling signaling or uplink scheduling signaling, so that the transmission performance is improved.

Optionally, the first spatial attribute parameter includes at least one of:

Sounding reference signal resource set indication information;

Sounding reference channel indication information;

Precoding information;

Antenna port information.

Optionally, the second spatial attribute parameter includes at least one of:

transmitting configuration indication information;

Precoding information;

Antenna port information.

The transmission configuration indication information (Transmission Configuration Indication, TCI) refers to that the network side device indicates quasi co-location of the downlink channel PDCCH, the (Demodulation reference signal (Demodulation REFERENCE SIGNAL, DMRS) antenna port information of the) PDSCH, and a certain downlink reference signal (e.g. SSB, CSI-RS). The quasi co-located attribute includes at least one of: doppler shift (Doppler shift), doppler spread (Doppler spread), average delay (AVERAGE DELAY), delay point difference (DELAY SPREAD), spatial RX parameter (spatial RX parameters).

It may be appreciated that the first transmission parameter or the second transmission parameter includes a transmission parameter corresponding to at least one of a subband, a bandwidth portion, and a carrier.

In addition, in the embodiment of the present application, the uplink transmission includes at least one of a physical uplink shared channel, a physical uplink control channel, and a channel sounding reference signal. The downlink transmission includes at least one of a physical downlink shared channel and a downlink reference signal.

Optionally, the first time domain unit and the second time domain unit are the same time domain unit; or the second time domain unit is behind the first time domain unit, and the time interval between the second time domain unit and the first time domain unit is larger than or equal to a preset value.

In the embodiment of the application, assuming that the first time domain unit is slot X and the second time domain unit is slot Y, then slot X and slot Y may be the same time slot, that is, x=y, or slot Y is after slot X, that is, Y > X, and the time interval between slot Y and slot X is greater than a preset value, that is, Y-X is greater than or equal to N, where N is a preset value.

In an optional embodiment of the present application, before the terminal device receives the downlink scheduling signaling or the uplink scheduling signaling in the first time domain unit, the method further includes:

the terminal equipment receives at least one target transmission parameter configured by the network side equipment; the first transmission parameter or the second transmission parameter includes the at least one target transmission parameter.

In the embodiment of the application, the network side equipment can pre-configure the target transmission parameters and send the target transmission parameters to the terminal equipment through the first message. When determining the first transmission parameter of uplink transmission or the second transmission parameter of downlink transmission, the terminal device may adopt the target transmission parameter configured by the network side device.

As an example, the uplink scheduling signaling or the downlink scheduling signaling may carry an enabling indication of the target transmission parameter. If the uplink scheduling signaling or the downlink scheduling signaling indicates that the target transmission parameter is started, the terminal equipment adopts the target transmission parameter configured by the network side equipment when determining the first transmission parameter of uplink transmission or the second transmission parameter of downlink transmission; otherwise, if the uplink scheduling signaling or the downlink scheduling signaling indicates that the target transmission parameter is not started, the terminal equipment does not adopt the target transmission parameter configured by the network side equipment when determining the first transmission parameter of uplink transmission or the second transmission parameter of downlink transmission.

It may be understood that if the network side device configures only one target transmission parameter, the enabling indication of the target transmission parameter carried in the uplink scheduling signaling or the downlink scheduling signaling may be 1bit of data, such as "0" or "1". If there are multiple target transmission parameters configured by the network side device, the enabling indication of the target transmission parameters carried in the uplink scheduling signaling or the downlink scheduling signaling may be a set or a list, and the indicator corresponding to each target transmission parameter is included, so as to accurately indicate which target transmission parameter is specifically enabled.

Optionally, the target transmission parameters include at least one set of spatial attributes; the space attribute group comprises space attribute parameters for uplink transmission and space attribute parameters for downlink transmission.

It should be noted that, the first spatial attribute parameter corresponding to the uplink transmission and the second spatial attribute parameter corresponding to the downlink transmission may both include the spatial attribute parameters in the spatial attribute group configured by the network side.

For example, if the DL grant received by the terminal device carries an enabling indication for the spatial attribute group, the terminal device may sample the spatial attribute parameters in the spatial attribute group when determining the first spatial attribute parameter corresponding to the uplink transmission, including the spatial attribute parameter for the uplink transmission and the spatial attribute parameter for the downlink transmission.

Likewise, if the UL grant received by the terminal device carries an enabling instruction for the spatial attribute group, the terminal device may sample the spatial attribute parameters in the spatial attribute group, including the spatial attribute parameters for uplink transmission and the spatial attribute parameters for downlink transmission, when determining the second spatial attribute parameter corresponding to downlink transmission.

Optionally, the spatial attribute parameters within the same spatial attribute group have different spatial characteristics. For example, in the same spatial attribute group, the spatial attribute parameter 1 for uplink transmission and the spatial attribute parameter 2 for downlink transmission correspond to different beams.

Optionally, the target transmission parameters include at least one uplink power control parameter set; the uplink power control parameter set includes a first power control parameter and a second power control parameter. The first power control parameter is used for uplink transmission of a time domain unit without downlink transmission; the second power control parameter is used for uplink transmission of the time domain unit with downlink transmission.

In an alternative embodiment of the application, the uplink transmission or the downlink transmission comprises at least one of:

the corresponding time domain resource is located after the first preset time and/or the corresponding time domain resource is located in uplink transmission or downlink transmission before the second preset time;

the transmission identifier is uplink transmission or downlink transmission of the first target identifier;

uplink transmission or downlink transmission which belongs to network configuration activation;

The priority is uplink or downlink of the first target priority.

In the embodiment of the present application, the uplink transmission indicated by the DL grant may be an uplink transmission with a transmission identifier being a first target identifier, or an uplink transmission that belongs to network configuration activation, or an uplink transmission with a priority being a first target priority.

Similarly, the downlink transmission indicated by the UL grant may be a downlink transmission whose transmission identifier is the first target identifier, or a downlink transmission that belongs to network configuration activation, or a downlink transmission whose priority is the first target priority.

The first target identifier and the first target priority may be configured locally by the terminal device, may be configured or indicated by the network side device, or may be specified by a protocol.

Optionally, the first preset time is indicated by the downlink scheduling signaling or the uplink scheduling signaling, and/or the second preset time is determined according to the first preset time and a time length configured in advance. Wherein the length of time may be preconfigured by the RRC.

In an optional embodiment of the present application, after the terminal device determines, according to the downlink scheduling signaling, a first transmission parameter corresponding to uplink transmission of the second time domain unit, the method further includes:

And the terminal equipment does not send the uplink transmission of the second time domain unit under the condition that the first preset condition is met.

Wherein the first preset condition includes at least one of:

the time interval between the first frequency domain resource where the uplink transmission is located and the second frequency domain resource where the downlink transmission is located in the second time domain unit is smaller than a first preset value;

and the first frequency domain resource where the uplink transmission is positioned and the second frequency domain resource where the downlink transmission or the guard band is positioned in the second time domain unit are overlapped.

The first predetermined value may be a predefined processing time (processing time), or a time interval of the network configuration, or a predefined processing time plus a time interval of the network configuration.

As an example, a terminal device receives a DL grant in a first time domain unit, and referring to fig. 7, a transmission parameter configuration schematic provided by an embodiment of the present application is shown. As shown in fig. 7, the terminal device receives a DL grant at slot X, where the DL grant is used for scheduling the PDSCH at slot Y, and determines, according to an indication of the DL grant, transmission parameters of the CG PUSCH of the UL subband of slot Y, including a power control parameter and a spatial characteristic.

The time interval (Gap) between the receiving time of the DL grant and the starting time of the CG PUSCH at slot Y is greater than a first predetermined value (timer), so after the UE receives the DL grant of slot X, the UE adopts the uplink transmission parameter indicated by the DL grant to transmit the CG PUSCH. If the time interval (Gap) between the time of receiving the DL grant and the time of starting the CG PUSCH at slot Y is less than a first predetermined value, the UE does not transmit uplink transmission of slot Y after receiving the DL grant of slot X.

Referring to fig. 8, another transmission parameter configuration schematic diagram provided in an embodiment of the present application is shown. As shown in fig. 8, the terminal device receives a DL grant for scheduling PDSCH in slot Y at slot X, and determines that UL sub-band (subband) of slot Y does not transmit uplink transmission of CG PUSCH according to an indication of the DL grant.

The time interval (Gap) between the reception timing of the DL grant and the start timing of the CG PUSCH at slot Y is greater than a first predetermined value (timeline). However, since the downlink transmission indicated by the DL grant overlaps with the frequency domain resource of the CG PUSCH, the UE does not transmit the CG PUSCH in slot Y according to the DL grant indication after receiving the DL grant in slot X.

In another optional embodiment of the present application, after the terminal device determines, according to the uplink scheduling signaling, a second transmission parameter corresponding to downlink transmission of a second time domain unit, the method further includes:

And the terminal equipment does not receive the downlink transmission of the second time domain unit under the condition that the second preset condition is met.

Wherein the second preset condition includes at least one of:

the time interval between the third frequency domain resource where the downlink transmission is located and the fourth frequency domain resource where the uplink transmission in the second time domain unit is located is smaller than the first preset value;

And the third frequency domain resource where the downlink transmission is positioned and the fourth frequency domain resource where the uplink transmission or the guard band is positioned in the second time domain unit are overlapped.

As another example, the terminal device receives the UL grant in the first time domain unit, and referring to fig. 9, another transmission parameter configuration schematic provided by the embodiment of the present application is shown. As shown in fig. 9, the terminal device receives an UL grant for scheduling PUSCH in slot Y at slot X, and determines transmission parameters of SPS PDSCH of DL subband of slot Y including spatial characteristics according to an indication of the UL grant.

The time interval (Gap) between the reception time of the UL grant and the start time of the SPS PDSCH at slot Y is greater than a first predetermined value (timer), so that the UE receives the SPS PDSCH using the SPS PDSCH transmission parameter indicated by the UL grant after receiving the UL grant of slot X. If the time interval (Gap) between the receiving time of the UL grant and the starting time of the SPS PDSCH at slot Y is smaller than a first predetermined value (timing), the UE does not receive downlink transmission of slot Y after receiving the UL grant of slot X.

Referring to fig. 10, a schematic diagram of still another transmission parameter configuration provided in an embodiment of the present application is shown. As shown in fig. 10, the terminal receives an UL grant for scheduling PUSCH in slot Y at slot X, and determines that DL subband of slot Y does not receive downlink transmission of SPS PDSCH according to an instruction of the UL grant.

The time interval (Gap) between the reception time of the UL grant and the start time of the SPS PDSCH at slot Y is greater than a first predetermined value (timing). However, since DG PUSCH overlaps with frequency domain resources of SPS PDSCH, UE does not receive SPS PDSCH in slot Y according to UL grant instruction after receiving UL grant of slot X.

Optionally, the method further comprises: and under the condition that the second preset condition is met, the terminal equipment does not start the hybrid automatic repeat request acknowledgement feedback corresponding to the downlink transmission.

As shown in fig. 10, since DG PUSCH overlaps with frequency domain resources of SPS PDSCH, UE does not receive SPS PDSCH in slot Y according to UL grant instruction after receiving UL grant of slot X. Further, the HARQ-ACK corresponding to the SPS PDSCH also does not need feedback.

Optionally, the frequency domain resource of the third frequency domain resource overlapping with the fourth frequency domain resource is not used for receiving the downlink transmission of the second time domain unit.

In the embodiment of the present application, the terminal device performs rate matching on the downlink transmission when the third frequency domain resource where the downlink transmission is located overlaps with the fourth frequency domain resource where at least one uplink transmission or guard band in the second time domain unit is located, and receives the downlink transmission after the rate matching on the frequency domain resource which does not overlap with the fourth frequency resource.

Referring to fig. 11, another transmission parameter configuration schematic diagram provided in an embodiment of the present application is shown. As shown in fig. 11, the terminal device receives an UL grant for scheduling PUSCH in slot Y at slot X, and determines transmission parameters of SPS PDSCH of DL subband of slot Y including rate matching parameters according to an indication of the UL grant.

The time interval (Gap) between the receiving time of the UL grant and the starting time of the SPS PDSCH at slot Y is greater than a first predetermined value (timer), but the DG PUSCH overlaps with the frequency domain resources of the SPS PDSCH, so after receiving the UL grant of slot X, the UE uses the rate matching parameters indicated by the UL grant to perform rate matching on the SPS PDSCH according to the DG PUSCH and the guard band, that is, receives the rate matched SPS PDSCH on the resources that do not overlap with the DG PUSCH and the guard band.

In an alternative embodiment of the application, the method further comprises: and the terminal equipment ignores the indication in the downlink scheduling signaling or the uplink scheduling signaling under the condition that the time interval between the first time domain unit and the second time domain unit is smaller than a second preset value.

In the embodiment of the present application, the UE receives the time domain resource (i.e., the first time domain unit) of the DL grant, and if the time interval between the UE and the time domain resource (i.e., the second time domain unit) of the uplink transmission is smaller than the second predetermined value, the UE may ignore the DL grant, that is, send the uplink transmission without using the uplink transmission parameter indicated by the DL grant. Likewise, the UE receives the time domain resource (i.e., the first time domain unit) of the UL grant, and if the time interval with the time domain resource (i.e., the second time domain unit) of the downlink transmission is less than the second predetermined value, the UE may ignore the UL grant, i.e., not receive the downlink transmission using the downlink reception parameter indicated by the UL grant.

Optionally, the uplink transmission or the downlink transmission includes uplink transmission or downlink transmission after a third preset time in the second time domain unit;

Wherein the third preset time includes at least one of the following:
